Machine: Windows 10 Pro 1803, Visual Studio Community 2017 15.8.1

Repro

1. Set build setting C++ Language Standard to ISO C++17 Standard (/std:c++17)
2. #include <chaiscript/chaiscript.hpp> in a source file
3. Compile

Expected

• Compiles without issue

Actual

• ChaiScript fails to compile

vcpkg\installed\x64-windows\include\chaiscript\dispatchkit\callable_traits.hpp(99): error C2825: 'T': must be a class or namespace when followed by '::'

This issue issue seems to be addressed in ChaiScript 6.1
